Application led January 28,1920. Serial No. 354,881.

To all whom it may concern Be it known that I, JOHN WALDHEIM, a. citizenof the United States, residinr in Elizabeth, in the county of Union andtate of New Jersey, have invented certain new and useful Improvements inCombined Typewriting and Computing Machines, of which the following isa. specification.

This invention relates to combined typewriting and computing machines,and isillustrated in connection with improvements disclosed in thecondin applications of Henry L. Pitman, erial o. 186,098, tiled August14, 1917, (now Patent No. 1,345,460, dated July 6, 1920) and Serial No.176,676,

filed June 25, 1917 (now Patent No. 1,360,'

145, dated November 23, 1920).

In 'the first-mentioned application, one or more column-totalizers areconnected with the typewriter carriage to travel therewith throughcomputing zones, and a cross-total izer is provided which may be made totravel through computing zones with the t pewriter carriage by meansofsuitable pic -up devices. In the second-named application,punctuation-skipping mechanism controlled by a column-totalizer isdisclosed.

ln carrying out the present invention, the machine, provided withcolumn-totalizers and a cross-totalizer, is also provided with apunctuation-skipping mechanism which may be controlled by acolumn-totalizer. Usually the cross-totalizer iS caused to travelthrough a com uting zone with a columntotalizer, and t epunctuation-skipping for both the column-totalizer and the cross-totalizer may be effected by the column-totalizer. Them however, thecross-totalizer is carried through a computing zone without acolumn-totalizer, the punctuation-skipping means will be ineffectiveunless some other means is provided. For this purpose, provision may bemade of means whereby the punctuation-skipping means may be controlledby the cross-totalizer when passing through a computing zone.

Other features and advantages will here inafter appear.

In the accompanying drawin s,

Figure l is a side view of an lnderwood addendagra h machine, showing myinvention applied thereto.

Fig. 2is a detail front elevation of the typewriter escapementmechanism, showing the same in. its usual position set for singleletter-space movement of the carriage.

Fig. 3 is a skeleton perspective of the punctuation-skipping mechanismshowing the connections whereby said punctuationskipping mechanism maybe controlled by either a. column-totalizer or a cross-totalizer.

F ig. 4 is a rear elevation, showing means whereby the cross-totalizercan be carried through 'a computing zone with the typewriter carriageand released when the passa e through the zone has been completed.

ig. 5 is a horizontal view, showing -the feelers by means of which thepunctuationskipping mechanism may be operated by either thecolumn-totalizer or the cross-totalizer.

Upon depression of character-keys, not shown, type-bars 1 will be swungupwardly and rearwardly to cause types 2 thereonto strike against aplaten 3 revolubly mounted by means of an axle 4 in a typewritercarriage 5. Said carriage 5' is mounted for movement across the machineby means Vof a roll 6 at the front thereof, lying in a groove in a rail7 of the frame, and at the rear by means of a rail 8, and is urgedtoward the left of the machine by means of a strap 9 and spring-drum 10.

Movement of the carriage 5 to the left, under the influence of saidstrap 9 and spring-drum 10, is controlled by means of escapementmechanism comprising a rack 11 pivotally supported on the carriage 5 bymeans of arms 12 and normally in mesh with a pinion 13. Said pinion 13has a one-way driving connection with the escapement wheel 14 by meansof pawls 15 and springs 16 thus enabling the typewriter carriage to bereturned to the right without reverse rotation of the escapement wheel.When each type-bar approaches the end of its printing stroke, a heel 17thereon is brought into engagement with a curved universal bar 18forming part of a frame 19 supported at the rear on pivoted arms 20. Theframe 1i) is then moved to the rear and aetuates the usual dog-rocker21, so as to throw the loose dog 22 out of engagement with theescapement wheel, and to bring the fixed dog 23 into e agementtherewith. As soon as .the loose og 22 passes out of engagement with theescapement wheel, it is swun to the left by spring 24 to a positiondetermlned by devices to be'describedhereinafter.

Upon return of the type-bar to its normal position, the frame 19 will bedrawn to the front by any suitable means, not shown, and the dog-rockerwill return to its normal position, under the influence of the spring24, thus bringingthe loose dog ain into engagement with the escapement weel, which, under the influence of the springdrum 10, will move theloose dog to its righthand limiting position against the action of thespring 24.

The typewriter carriage is connected by means of arms 25 with acolumn-totalizer carriage 26, which may be mounted to travel along a4rail 27 secured to the frame of the machine, by means of balls 28 runninin opposed V grooves in the carriage 26 an the rail 27, respectively.One or more adjustable column-totalizers 29 are positioned on thetotalizer carriage 26 by means of teeth 3() on the totalizer engagingwith teeth 30* on the totalizer carriage, and the totalizers are held inplace by means of dogs 31 on the totalizers engaging in grooves 32 inthe to talizer carriage. Each totalizer 29 is provided with the usualdialwheels 33 andcomputing Wheels 33, which, in passing through acomputing zone1 are brought into successive engagement with, and areactuated by, a master wheel 34. The master wheel 34 may be actuated bymeans such as those more fully described in said eopending applicationNo. 186,098.

Provision may also be made of a cross-totalizer 35 of the same generalconstruction as the column-totalizers 29, and provided with dial wheels36 and with computing wheels 37, which are brought successively intoengagement with, and are actuated by a master wheel 38, which may beactuated by the numeral keys by means more fully described in saidco-pending application No. 186,098. Said cross-totalizer 35 is alsoadjustably positioned on cross-totalizer carrage 39 by means of teeth 40on the crosstotalizer engaging with teeth 41 on the crosstotalizercarriage, and maintained in such position by means of dog 42 extendinginto a groove 43, the cross-totalizer carriage being mounted formovement, along a rail 44, by means of balls 45 engaging in opposedV-shaped grooves in the cross-totalizer carria e 39 and rail 44,respectively.

n order to rapidly position the carriage in computing zones, provisionmay be made of a rack 46 on whichstops 47 may be adjustably positionedto be engaged by tabulator plungers 48. Such tabulator stops 47 may beutilized in picking up the cross-td talizer t0 carry it through acomputing zone with the typewriter carriage. In performing thisoperation, each stop 47 engages a pickup hook 49 on a pick-up bar 50pivoted at 51 on a slide bar 52, and carries both the bar 50 and slidebar 52 with the carriage through a computing zone. The bar 50 1sieldingly supported by means of a lever 53 having a fol ower 54 to beengaged by an edge portion 55 of the bar, duringmovement of the latterwith the carriage, saidlever 53 being pivoted at 56 and urged by spring57- to press the follower 54`against the edge portion 55 of the bar 50.A stop 58 is provided to limit'the upper movement of the follower 54,and the pick-up bar 50 is rovided with depressions 59 and 60 to a lowthe pick-up bar to be depressed when in its normal position and at thetime when it is lcarried out of the computing zone.

The control of the pick-up bar 50 is also effected by means of `a pin 61on said bar engaging in a slot 62 on a plate 63, secured to a fixed partof the frame. A cam 64 at one end of the slot is engaged by a pin 61when the pick-up bar 50 is in its normal position and insures depressionof said bar 50 in such normal position. The pick-up hook is providedwith a slot '65 of suitable width to receive a stop 47, and has cams 66and 67 at the right and left, respectively, of said slot, looking at themachine from the front, the left-hand cam 67 extending upwardly beyondthe right-hand cam 66.

The operation of a stop 47 on the pick-up hook 49 is vas follows. As thestop 47 enters a computing zone, it passes over the cam 66 and engagesthe upper part of the cam 67 and carries the hook 49 to the left. Thepin 61 then passes out of engagement with the cam 64, and the follower54 is brought into engagement with the lower edge portion 55 of thepick-up bar 50, thereby causing the pick-up hook 49 to be lifted, sothat the sto 47 will extend into the slot 65. This re ation between theparts is maintained until the pin 61 is brought into engagement with acam 68, and the depression 60 is brought into position abovev thefollower 54. The pick-up bar 50 will then be depressed and the pick-uphook 49 de pressed, so as to break the connection between the same andthe stop 47.

The advance movement of the hook 49 .is transmitted from the slide 52 bymeans of a rack 69 thereon to a toothed segment 70 on a stub shaft 71,the motion of the toothed segment 70 being'transmitted in turn by asecond toothed segment 70* to a pinion 72 at the rear end of theforwardly extending shaft 73. A pinion 74 at the forward end of theshaft meshes with a rack 75 on the cross-totalizer carriage 39, andthese parts serve to transmit the movement of the shaft 73 to thecrosstotalizer carriage.

Upon release of the pick-up hook 49 from the stop 47, thecross-totalizer carriage amd the connections between 4the same and thepick-up hook 49 may be restored to their normal positions by anysuitable means, such as those disclosed in said prior application No.186,098. The structure so far described is in general the same as thatdescribed in said a plication No. 186,098.

The dial whee s 33 in each column-totalizer are arranged so as toprovide suitable punctuation spaces, and in order to prevent thetypewriting of figures in punctuation spaces, provision is made of aplurality of cams 76 on the column-totalizer. In passing through acomputing zone, said cams 76 are brought into engagement at the propertimes with a trip member 77 pivoted at 77 on a lever 78 mounted on afixed pivot 79, a sprin 80 connected to said trip member 77 yiel inglyholding the same against-a pin 81, so that4 the tri 77'will be heldagainst movement relatively to leverv78 when the totalizer is passingthrough a Qomputin zone in the normal operation of the machine but willbe permitted to yield when the totalizer is returned to the ri ht ofthe' machine. The lever 78 and trip 7 may be considered as a feeler tocoperate with a column-totalizer. The movement- Of the lever 78 istransmitted by pivot pin 82 to a link 83 pivoted to the upper end oflever 84 pivoted at 85 on a fixed part of the frame. A link 86 pivotedat 87 to the lower end 0f lever 84 connects said lever to an arm 88rotatably supported on a post 89, and urged forwardly by means of aspring 90 connected at one end to a pin 91 on said post 89 and at theother end with said arm 88. It will be seen that the action of thespring tends to hold the tri 77 in position to be engaged by the cams 6.

Fixed with reference to arm 88 is an arm 92 provided with a Stop 93normally in the path of the loose dog 22 to limit the movement of thelatter when released from the escapement wheel, thereby determining aletter-space feeding movement of the carriage. When, however, the trip77 is actuated by cam 76, the stop 93 is moved forwardly so that a notch94 in said arm 92 is brought opposite the loose dog 22, thus permittingmovement of the latter until it is brought into contact with a fixedstop 95, and determining a double letter-space movement of the carriage.The unctuationskipping mechanism thus described in general may be thesame as that disclosed in said ap lication No. 176,676.

Usually the cross-totalizer Ais carried through a computing zone inconnection with the travel of the column-totalizer through the saidzone. Under such conditions, it is evident that the control of thepunctuation-skipping means for the columntotalizer will produce the sameresult for the cross-totalizer. In case the crosstotal izer, however, iscarried through a. computing zone with a column-totalizer, thepunctuation-skipping means just described will be ineffective.

In order to obtain automatic punctuation-skippingA for across-totalizer, in case it is carried through a computing zoneindeendently of a column-totalizer, provision 1s made of a series ofcams 96, which, in passing through a computing zone, engage a trip 97pivoted at 98 on afeeler arin 99, and yieldingly held by a spring 100against a lpin 101 on said arm 99, so that when engaged by the cams 96,the trip 97 will be held against movement on the arm 99, and, on thereturn movement of the cross-totalizer, the tri 97 may yield and preventactuation of t e arm 99 by the cams, 96. The feelerarm 99 is fixed onthe lower end' of a shaft 102 mounted in brackets 103 on the frame ofthe machine, and another arm 104 fixed on the shaft 102 at its upper endengages pin 82 by means of a fork 105 at -the forward end of said arm104 embracing said pin 82. 4

It will be evident that with the present structure thepunctuation-skipping mechanism will be rendered effective automaticallyby either a column-totalizer or a cross-totalizer, or when both arecarried through a computing zone together.
